This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X45S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X45S in place of this model. The MBLD replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X45S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X45S is a double-acting, double-rod aluminum mini cylinder: a rod exits both ends of the Ø20mm bore, so push and pull force are equal. This model is discontinued — the drop-in replacement is the MBLD20X45S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X45S
The AirTAC MALD20X45S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, delivering equal force both ways at 132 N each direction at 0.5 MPa. The exact drop-in replacement is the MBLD20X45S, matching the 20 mm bore, 45 mm stroke, G1/8 port, and mounting.
This -S SKU includes a magnet for CS1-M or DS1-M switches; the MBLD upgrade shifts to CMSG, DMSG, or EMSG sensors. The MALD uses threaded covers, whereas the MBLD features a riveted rolling-packed body. It has no back cover or SDB option, so you mount it directly on the body, or via FA flange and LB foot. End-of-stroke energy is absorbed by a fixed rubber bumper, not an adjustable cushion.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X45S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X45S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X45S |
| Bore size | Ø20 mm |
| Stroke | 45 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 300 mm |
Double-rod types have no back-cover code and no SDB pivot; mount on the body, LB foot or FA flange. The MBLD20X45S carries the same ratings.
Output Force — Equal Both Ways (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 132 N | 132 N |
| 0.7 MPa | 185 N | 185 N |
| Max (@1.0 MPa) | 27 kgf | |
A rod exits both ends, so the effective area — and force — is equal in both directions. The MBLD20X45S matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD20X45S
| MALD | Double-rod aluminum mini cylinder, double acting (discontinued). |

| ×45 | Stroke length in mm. |
| S | Optional magnet for a CS1-M / DS1-M sensor (MBLD uses CMSG/DMSG/EMSG). |
Replacement: MALD → MBLD. No back-cover (CA/U/CM) and no SDB on double-rod. Mounting: LB / FA.
Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X45S Is Used
PCB Edge Guiding
Uses the 132 N equal push and pull force to center electronic circuit boards on a conveyor without rotating the fixture.
Dual-End Tooling Transfer
The twin M8 rods allow a rear cam to trip a mechanical switch while the front rod pushes a lightweight plastic part.
Label Dispenser Feed
The fixed rubber bumper provides a soft, repeatable end-stop for a 45 mm label peeling stroke in packaging machines.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X45S with MBLD20X45S
To replace the MALD20X45S, specify the MBLD20X45S and confirm your G1/8 port, M8x1.25 rod thread, and FA or LB mounting. Because there is no back-cover code or SDB, verify your body-mount geometry. The -S magnet requires changing your CS1-M or DS1-M switches to the MBLD's CMSG, DMSG, or EMSG equivalents.
Size on the equal 132 N force at 0.5 MPa. If you need less holding power, step down is not possible as 20 mm is the smallest bore. To step up, the next size is the 25 mm bore, which provides 206 N at 0.5 MPa.
Upgrade checklist
- ✓ Order the MBLD20X45S (same bore/stroke/force)
- ✓ Force equal both ways (132 N at 0.5 MPa)
- ✓ Twin rods for anti-rotation / rear flag
- ✓ No back cover / SDB — plan a body or FA/LB mount
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check Protect both rod ends from side load on long strokes.
- check No back-cover / SDB on double-rod — use body / FA / LB.
- check Front/rear covers are threaded — not for field disassembly.
- check For new builds, specify the MBLD20X45S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X45S FAQ
Yes, the MALD20X45S is discontinued. The exact drop-in replacement is the MBLD20X45S, which matches the 20 mm bore, 45 mm stroke, G1/8 port, and equal force. You will need to update your sensors from CS1-M or DS1-M to the CMSG, DMSG, or EMSG family.
Because a rod exits both ends, the piston sees the same annulus area in both directions, making push and pull force equal. The ratings are 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa. The fixed rubber bumper softens the impact at these forces but does not lock the load on air loss.
